Steel line is cheap. Just get a piece from the local parts store.

But, if what you have in there now is working fine, leave it alone. It's always those "simple" jobs that turn into nightmares.

 

No truer words have been spoken! My brake lines are all fine now. I kinda had to learn the hard way a few months back when I replaced all the brake hoses and wheel cylinders. Every one of the brake lines twisted off when I went to take off the flare nuts. No amount of PB Blaster made a difference. I could have saved a few headaches just cutting the brake line behind the nut and reflaring with a new fitting. That's what I ended up doing in a roundabout way to some of the lines (others I just replaced them entirely). But this is what happens when you do a job for the first time. The simple jobs turn into nightmares.

 

I worked on a "Furrin" car once years ago that had broken a short brake line three times before it got to me. I say "Furrin" because I don't remember what it was. I think it was a Borgward, but I don't remember. I made the new one MUCH longer and coiled the line with three turns. You see that near master cylinders a lot. The coil allows it to flex and you can bend it slightly to line the nuts to the holes.
